ROBERT L. BENSON, OF CHICAGO, ILLINOIS.

NEBULIZER.

SPECIFICATION forming part of Letters Patent No. 733,364, dated July 14, 1903.

Application filed September 24, 1900. Serial No. 30,908. (No model.)

To all whom it may concern:

Be it known that I, ROBERT L. BENSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Nebulizers, (Case No. 3,) of

. which the following is a full, clear, concise,

and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to nebulizers em ployed principally in the treatment of diseases of the respiratory tract, and has for its object the improvement in the construction of the ducts employed for subdividing the medicament.

Generally speaking, my invention comprises in its preferred embodiment an induction-tube for conveying air under pressure, which is adapted to project within a bottle or other suitable reservoir containing a medi cament, the induction-tube being provided with a duct extending transversely thereto, preferably at an angle slightly acute, a sleeve being mounted upon the ind notion-tube and movable longitudinally thereof, and a second duct fixed with relation to the sleeve and extending, preferably, longitudinally thereof, the sleeve by being movable longitudinally with respect to the induction-tube permitting relative adjustment between the said ducts, whereby the action of the apparatus can be regulated and adjustment for wear and misconstruction readily effected.

In the preferred embodiment of the invention the sleeve is provided with an openended slot that receives the duct carried by the induction tube, whereby angular displacement of the ducts with respect to each other is prevented.

I will explain my invention more fully by reference to the accompanying drawings, illustrating the preferred embodiment thereof, in which- Figure 1 is a view in elevation of a device constructed in accordance with my invention, a containing vessel being shown in section. Fig. 2 is a sectional elevation of the device of my invention, the parts thereof being separated, more clearly to illustrate the nature of its construction. Fig. 3 is a view in elevation of the device, taken in another direction to show the method of preventing angular displacement between the ducts.

Like parts are indicated by similar characters of reference throughout the different figures.

I have illustrated one form of a vessel a that contains medicament or other liquid 1), which is discharged through the eductionpipe 0 when the sealing screw-plug d is removed therefrom. The eduction pipe or tube 0 is contained within the stopper 6, through which the induction-tubef also passes. The ind notion-tube conveys air under pressure to the interior of the bottle and is provided at its lower end with a duct g, extending transversely to the tube f, being preferably disposed at an angle that is slightly acute with respect to the induction-tube. The air that is conveyed through the latter tube under pressure is forced through the duct g and in its passage serves to efiect the passage of the medicament I) through the duct it, that is mounted upon the sleeve 2 that snugly fits but is longitudinally movable with respect to the tubef. The sleeve t, by being thus movable upon the tube f, serves to permit adjustment between the ducts g and h,whereby the relative position of the mouths of the ducts may be adjusted for-the purposes desired. The medicament is vaporized by the action of the stream of air flowing through the duct g upon the stream of medicament drawn through the duct h, the vaporized material being passed through the tube a. It will be observed that the bore of duct his transverse with respect to the bore of duct g and that the mouths of these ducts are adjacent, whereby a stream issuing from one duct may pass athwart the stream issuing from the other duct. In order that the ducts may not be angularly displaced with respect to each other, I preferably provide the sleeve 2' with a slot 713 at its upper end, the upper end of the slot being opened, whereby the duct g may be readily inserted therein, the duct by engaging the longitudinal edges of the slot .serving to prevent the sleeve from being robated upon the tube f.

It is obvious that changes may readily be made from the embodiment of my invention herein shown and particularly described, and I do not therefore wish to be limitedto the precise construction shown; but,

Having thus described my invention, I claim as new and desire to secure by 'Letters Patent The combination with an induction-tube, of a duct extending transversely therefrom and communicating therewith, a sleeve longitudinally movable upon the induction-tube, and a second duct for conveying medicament, the duct upon the induction-tube serving to effect the passage of the liquid through the remaining duct, the sleeve permitting adjustment between the ducts, the said sleeve being also provided with a slot with which the duct ,upon the induction tube is engaged, whereby angular displacement of the ducts with respect to each other is prevented, substantially as described.

In witness whereof I hereunto subscribe my name this 15th day of September, A. D. 1900.
